Title

the golf ball

Problem Scenario

I sell golf ball i want to tell my costumers if the ball has a lot of roll on it or not or how many layers a certain golf ball has.

Broad Question

what ball rolls farther a woman's or a Men's.

Specific Question

If a man and woman's golf balls are hit with the same force which will have the greatest distance?

Hypothesis

If a men's and women's golf ball are hit from with the same force then the Men's ball will roll further, because it is heavier.

Variables

Independent Variable:

=Different type of ball

Dependent Variable:

=Distance ball rolls

Variables That Need To Be Controlled:

- the force the ball is hit from, the release of the balls, the surface the balls hit.

General Plan

-get the golf ball
-create the thing that rolls the ball
-track the data
-put stuff on the poster board
-science fair day

Potential Problems And Solutions

-The golf ball could be hit with different forces
- the golf ball could hit something on the floor like dirt, pencil, and such.

Safety Or Environmental Concerns

-The ball could hit some one
-The ball could go crazy and fling across the room

Experimental Design

two golf balls

Number of Comparison Samples

There will be four comparison samples

Number Of Observation In Each Sample:

I will take four observations

When data will be collected

3/18/13

science room.

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
Woman's ball	1	At my family golf course	0
men's ball	1	At my family golf course	0
wood	7	from my house	0

Detailed Procedure

1. get the means and woman's golf balls.
2. Get wood for the stand that rolles the balls.
3. make a stand to role the balls off.
4. measure the distance the ball rolls.
5. graph on the poster bored.

Results

My Hypothesis said the woman's ball would roll father but i was correct, The Men's ball rolled quite a bit father. The women's ball averaged 7.0104 meters, and the Men's ball averaged 8.6106 meters. The ball hitter I used to hit the ball worked out pretty well. The way I knew I hit the ball with the same force was that I put a ruler in back of the ball hitter. The way I used it was that I pulled the wooden head back to 8.5 inches. I thought that was a good speed.

Conclusion

The experiment worked out how I planned it would. The ball hitter was also successful it hit the ball straight and perfect. I had to do the experiment on the tile floor because I could not get turf in time. Even though I did that they still rolled fine. Like I said in my Results paragraph, I was correct on what ball I thought would roll father.

Discussion

My experiment went very well. Like I said before I was correct on my experiment, some problems in the experiment were when I first hit the ball with the wooded ball hitter then when the ball got hit on the top of the ball, I solved my problem by lowering the wooden ball hitter lower to the ground. After that I solved my problem. Another problem I had was I did not sweep the floor before so the ball went every where, when I figured out what was happening I swept the floor. If I was going to change something in my experiment I would change instead of rolling the ball on tile floor I would roll it on turf. In my next time paragraph I also said next time I will research the difference between a hard covered balls and soft covered balls and ball compression. The reason I want to that is because I thought that would be interesting, I also always want to the know the ball compression and how hard and soft the ball is. Another reason I want to is because I love golf and I could answer a lot of questions people have about golf and golf balls.

Background Research

In my science fair project I researched a lot because I had to figure out how many dimples on the ball and such like that. Some of the researched I called the Callaway golf ball company, I also called the Maxfli noodle ice golf ball company I called those two company's for how many dimples are in each of those ball. I also went on GolfBallPlanet.com to find out the Compression of the ball how many layers each ball has and what the cover of the golf ball is made of. I need that research from GolfBallPlanet.com because I need that information for my display item.

During my Research I decided to find out how dense a golf ball is and I also found out how many dimples each ball has. For density for the men's ball is 1.15 and the density of the women's ball is 1.13. I thought that was interesting because the men's ball rolled so much farther and the density was so close together. I thought then I found out a solution and it was more of how many dimples there was on the ball the shortest distance the ball went because of the fiction. The fiction made the ball slow down. The men's ball had 386 dimple and the women's ball had 408 dimples.

Abstract

What rolls farther Men's? or Women's?

Josh Rivers

I did my project on the distance men's and women's golf balls travel and which one travels farther. In order to do this experiment I had to get this contraption that would putt the balls. My science teacher Mr. Groves had this stand made of wood that he let me use for the putting. I fixed the wooden stand up a little bit and I made it so there is a wooden swinger on the wooden stand. To be able to make that swinger work I had to take out some screws and put them in different places. Now since the wooden putter was made I could move onto the next step. I had to sweep the tile floor because I did not want the dust or little pieces of dirt to make the golf ball go an opposite way. During my experiment I did four trials. When I was doing the experiment I was taking all the numbers and averaging it because I did not want too many numbers. The way I measured the distance each ball went, was I used meters, because meters is more precise and scientific than feet. After I got all my measurements, I put them on a spreadsheet and made the averaged numbers into a graph. The two averaged numbers showed that the women's ball averaged 7.0104 meters, and the men's ball averaged 8.6106 meters. It wasn't until the experiment was over that Mr. Groves and I discovered that the amount of dimples in the ball might have had an effect on the roll of the golf ball. The women’s ball had more dimples than the men’s ball. Having more dimples may have caused more friction on the women’s ball, slowing the roll down. The men’s ball drove farther. That was the end of my experiment. After that I had to move on to do my poster board. With my poster board complete, I was basically done with the experiment all I will have to do is wait till the 29th for the Science Fair.
